Half Marathon Sub-1:35 Plan

This 12-week Sub-1:35 Half Marathon Plan—developed by Olympian Ilya Tyapkin—uses a phased structure that blends intervals, tempos, long runs, and recovery to build peak endurance and speed. Designed for advanced runners with a solid base, it brings you to race day fresh, sharp, and ready to sustain ~4:30/km (7:15/mi).
